The Condorcet loser criterion states that "if a prospect would eliminate a head-to-head Competitiveness versus every single other candidate, then that applicant have to not get the overall election".

The independence of irrelevant alternate options criterion states that "the election consequence stays precisely the same regardless of whether a prospect who can not gain decides to run." In the general circumstance, instantaneous-runoff voting could be vulnerable to strategic nomination: if a candidate decides to run in any respect can have an effect on the result even though the new prospect cannot themselves win.[fifty six] This is much less likely to happen than under plurality.[citation necessary]
